GUN-LOCK.

' SPECIFICATION forming part of Letters Patent No.`468,004, dated February 2, 1892. Application led September 19.1891. Serial No. 406,276. No model.)

ATo all whom it may concern.-

Be it known that I, THOMAS J. LocKWooD, of Muncie, county of Delaware, and State of Indiana, have invented certain new and 'usef ul Improvements in Gun-Locks; andI do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, in which like figures refer tulike parts. i

My invention relates to the construction of double-lock mechanism for guns; and it consists in the arrangement of the several parts so that either trigger may operate either lock independently or both locks successively, and is applicable both to the ordinary hammergun aswell as what is called the ham1nerless gun, and is an improvement upon the mechanism shown in the application led by me on the 2d day of August, 1890, Serial No. 360,754, and in a second application filed by me on the' 13th day of April, 1891, Serial No. 388,639, and will be understood from the following description.

' In the. drawings, Figure 1 is a side view, partly in section, showing my device applied to a hammerless gun. Fig. 2 is a top view of the lever mechanism, showing both hammers raised. Fig. 3'is a similar View showing one hammer down. Fig. 4 is an enlarged per- '4 being hinged together by a pivot-bolt 7.

@tions 9 at their ffii'ward ends for engagi ith the hammers" and have dovetailedprogections 20 on the bottom, which t in corresponding grooves in the sears. 10 are springs secured .to the casing and which bear against the rear end 11 of the levers for returning them to their'normal posi'- tion.

speotive view of the two levers detached. Fig. l

Fig. v6 is a.

5 is the dog, and 6 the 'shank of the sear", which is jointed, as shown in'Fig. 1, the parts 8 are reciprocating levers, which" are pro! upon the inner face of one of the levers, the opposite lever'having a pin 13. When both hammers are cocked and the levers are in the position shown in Fig. 2, by pulling upon either trigger the pin 13 will have a free movement in the vertical slot 1.2 of the opposite lever, and when pressure on thev trigger 1s released and the searwith its lever drops back into place the spring 10 at the end of that lever forces the lever forward on the sear, car- 12 are horizontal and vertical grooves formed rying the pin 13 into th'e horizontal groove 12,V

locking together both levers and through them the sears. In this case either barrel may be discharged by either trigger. Thesetriggers are shown at 15 and 16.

14 is a central block which is slotted to admit the triggers in the usual manner.

In the modification shown in Figs. 5, 6, and 7 the levers 8 have beveled arms 9 at one end, l

which engage with the hammers when raised, and at the opposite end are enlargements 11, the inner face of one having vertical and horizontal grooves 12, which engage with the pm 13 on the opposite lever in the same manner as shown in Fig. 4. When in the position` shown in Fig. 6, the pin is in the center of the grooves or at the point where the two grooves cross. Each lever rests at a littleto one side of its center in a bracket 19, which is formed der side `of each lever is a hook 17. In this case the sear issingle, its dog' 5 and shankf the leverwhenthe hammer is cocked.. Both hammers being'raised, as shown ln'Flg. 6, and

the levers being locked with their sears, when the right-hand trigger isl pulled the pressure` of the spring 10 on theend will force the rightvon either sides of the block 14, and on the unhand lever 'forward,releasing it from engagev 'ment with the sear, and at the same time the pin will enter the horizontal groove on the lever', therebylocking bot-h levers together, so

vthat-when the same trigger v1s again pulled v both levers will be operated, thereby ring the remaining barrel and operating only upon' that Sear.

' The advantage .of this arrangement over the other is that eitherbarrel may be fired fby its own trigger and the remaining barrel by either trigger, and both sears are ICO ' other by means of never operated on together, for the reason that as soon as one barrel is fired the sear on that side is released from engagement with its le ver and will not again cocked. v

On comparison of the two forms it will be seen that the form and operation of the levers are substantially the same in both cases, the only dilerence being that in the one case the 'engagement of the lever with the sear is made by means of thedovetailed groove and in the the hooks. What I claim as my invention, and desire ,to secure by Letters Patent, is the following:

1. In a gun, a double-lock mechanism, independent spring-controlled levers supported upon a block connected to the casing between ihelocks, the forward ends of the levers having projections for engaging withthe hammers when the latter are raised, the rear ends y of such lever provided with projections, one

. vertical and horizontal grooves for receiving of these projections having a pin and the other such pin, such projections on the lever resting uponthetriggers,hooksformedupon thelevers behind the supporting-block, and sears pivoperate until that hammer is v l oted belowsncli levers and having hooks on their rear ends for engaging the hooks formed upon the levers, the pulling of either trigger operating to lock the levers together, whereby the remaining barrel may be tired by either trigger, substantially as shown and described.

In a gun, a double-lock mechanism, a' pair 0i" independent levers working in suitable bearings and having projections on their forward ends for contacting with the hammers when raised, the rear ends of such levers adapted to engage with each other by means of a pin formed upon one and vert-ical and horizon tal grooves upon the other, sears locked to the levers when the'hammers are raised, and the levers locked together when one barrel is fired, whereby the remaining barrel may be tired by either trigger, substantially as shown and described.

In witness whereof I have hereunto set my hand this 10th day of September, 1891.

THOMAS J. LOCKWOOD.
